Superplasticisers
Oscrete Performance Additives has a comprehensive range of powder superplasticiser to cover a variety of applications.
Superplasticisers can be used in three ways: to create flowing, self-leveling concrete without increasing water, without reducing cement and without sacrificing strength; to produce workable, high-strength concrete by reducing the water and thus the water-cement ratio; or, to save cement by reducing both the water and cement contents while maintaining the same water-cement ratio and the same workability.
The main benefits of superplasticisers can be summarised as follows:
Increased fluidity:
- Flowing
- Self-leveling
- Self-compacting concrete
- Penetration and compaction around dense reinforcement
Reduced W/C Ratio:
- High early strength
- Higher ultimate strengths
- Reduced shrinkage, especially if combined with reduced cement content
- Improved durability.
